Abstract
The invention relates to a method for blocking up a plastic cable conduit. In the method, a cavity is formed between a cable and a plastic conduit wall at the end part of the cable through a front baffle and a rear baffle; plastic rubber which is the same with the material of the plastic conduit wall is poured into the cavity to carry out blocking; and after being cured, the plastic rubber is molten with the plastic conduit wall into one whole body. In the method in which the technical scheme is adopted, the cavity is formed between the cable and the plastic conduit wall through the front baffle and the rear baffle; the plastic rubber which is the same with the material of the plastic conduit wall is poured into the cavity to carry out blocking; after being cured, the plastic rubber is molten with the plastic conduit wall into one whole body; and due to the same coefficient of thermal expansion, an interface cannot be generated between the blocking material and the conduit wall, so that the aim of totally blocking is fulfilled.
Description
Technical field
The present invention relates to the wireline operation field, specifically relate to the method for shutoff plastic cement cable tube, and relate to plastic cement cable tube obtained by this method.
Background technology
In recent years, along with the develop rapidly that power cable is built, it is underground that cable duct is clouded in the city just as a rule giant dragon, and the pipeline waterproof shutoff is applied in transformer station, Gong Jing, the underground station, sub-district by increasing.Thereby the waterproof plugging effect of worker's well, transformer station, underground station, sub-district, switch cubicle directly influences the fail safe of equipment, cable operation.
In original cable method for blocking, because shutoff material and cable tube wall material are inconsistent, the gap appears in meeting of long duration.Like 200920208533.3 patents, be bonded and sealed in the time of between resin after the expansion and the tube wall, long-time back the gap occurs and produces seepage because thermal coefficient of expansion is different.
Summary of the invention
What the present invention will solve is slit and leakage problems after the cable shutoff, to occur, and a kind of method of shutoff plastic cement cable is provided, and plastic cement cable obtained by this method is provided.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
A kind of method of shutoff plastic cement cable tube in the end of cable, forms cavity with front apron and backboard between cable and plastic cement tube wall, in cavity, inject the plastic cement shutoff with the identical material of plastic cement tube wall; After plastic cement solidifies, with the fusion of plastic cement tube wall be one.
Shutoff plastic cement cable tube by said method makes in the end of cable, is provided with front apron and backboard between cable and the plastic cement tube wall; In by the cavity that tube wall, front apron and backboard surrounded, be filled with the plastic cement melt; On said front apron, have sprue.
Described sprue is positioned at the bottom of front apron.
Adopt the present invention of technique scheme, between cable and plastic cement tube wall, form cavity, in cavity, inject plastic cement shutoff with the identical material of plastic cement tube wall with front apron and backboard; After plastic cement solidifies, with the fusion of plastic cement tube wall be one because thermal coefficient of expansion is identical, interface can occur between plugging material and the tube wall, thereby reach complete shutoff.
Description of drawings
Fig. 1 is an overall structure sketch map of the present invention.
Embodiment
As shown in Figure 1, the method for shutoff plastic cement cable tube of the present invention in the end of cable 2, forms cavity with front apron 3 and backboard 4 between cable 2 and plastic cement tube wall 1, in cavity, injects the plastic cement shutoff with plastic cement tube wall 1 identical material; After plastic cement solidifies, with 1 fusion of plastic cement tube wall be one.Like this, because thermal coefficient of expansion is identical, interface can occur between plugging material and the tube wall, thereby reach complete shutoff.
Shutoff plastic cement cable tube by said method makes in the end of cable 2, is provided with front apron 3 and backboard 4 between cable 2 and the plastic cement tube wall 1, certainly, the center of above-mentioned front apron 3 and backboard 4 all needs perforate to pass to make things convenient for cable 2.Then, in the cavity that is surrounded by tube wall 1, front apron 3 and backboard 4, fill plastic cement melt 6.During filling, need be on the top on the front apron 3 or the bottom have sprue 5, with the convenient plastic cement melt 6 that injects with the identical material of tube wall.
Claims (3)
1. the method for a shutoff plastic cement cable tube; It is characterized in that: end in cable (2); Between cable (2) and plastic cement tube wall (1), form cavity with front apron (3) and backboard (4), in cavity, inject plastic cement shutoff with the identical material of plastic cement tube wall (1); After plastic cement solidifies, with plastic cement tube wall (1) fusion be one.
2. the shutoff plastic cement cable tube that is made by the said method of claim 1 is characterized in that: the end in cable (2) is provided with front apron (3) and backboard (4) between cable (2) and the plastic cement tube wall (1); In the cavity that is surrounded by tube wall (1), front apron (3) and backboard (4), be filled with plastic cement melt (6); On said front apron (3), have sprue (5).
3. shutoff plastic cement cable tube according to claim 2 is characterized in that: described sprue (5) is positioned at the bottom of front apron (3).
